WEATHER-STRIP FOR DOORS.

Specification a Letters Patent.

Patented Aug. is, 1908.

Application filed April 1907i Serial No. 370,245.

T all whom it may concern:

Be it known that I, WILLIAM MALOTT, of the city of Toronto, in thecounty of York, in the Province of Ontario, Canada, have in- .i ventedcertain new and useful Improvements in Weather-Strips for Doors, ofwhich the following is the specification.

My invention relates to improvements in weather strips for doors, andthe object of the invention is to devise an extremely simple stripapplicable to the bottom of a door, which will effectually exclude thedraft when the door is closed, and which when the door is being closedwill automatically close the crevice at the bottom of the door and yetwill rise immediately the door is released in opening.

A further object is to make a weather strip applicable to the bottom ofthe door, which is not liable to get out of order or wear out and inwhich there will be practically no friction in throwing the strip intoposition to exclude the draft.

My invention consists essentially of a strip of spring metal preferablybrass extending longitudinally underneath the bottom of the door, astrip preferably of galvanized iron or zinc into which one edge of theaforesaid strip fits, the said galvanized strip being curled or formedup to receive the longitudinal pivotal rod, end plates forming a journal for the ends of the rod, a counter-balancing bar extendinglongitudinally to one side of the pivotal rod, and an arm connected tothe bar and extending through an areshaped slot on one of the end platesand a bracket on the frame of the door jamb with which the end of thearm is designed to contact to throw thestrip down to close the crevice,the parts being otherwise arranged and constructed as hereinafter morepar ticularly explained.

Figure 1, is a perspective view of the bot: tom of a door showing myinvention applied thereto and the door nearly closed. Fig. 2, is asimilar view showing the door ajar. Fig. 3, is an enlarged crosssectional detail.

In the drawings like letters of reference indicate corresponding arts ineach figure.

A is the door and B the jambs thereof.

C is a bracket secured to the jamb B near the bottom of the faceadjacent to the edge of the door.

D and D are end plates secured to the edges of the door at the bottom.

E is a strip made preferably of brass and F is a strip made preferablyof zinc or galvanized iron having a fold F into which one edge ofthestrip 'E' fits. The strip F is also provided with a curled forwardend F through which extends a rod G, which is journaled at the end inthe end plates D or the rod may be held stationary in the end plates,and the curled end F of the strip F may be journaled thereon as may befound best. A

II is a counter-balancing bar, which is secured by rivets H on the upperside of the strip F, the rivets extending through they strips E and F.

D is a supplemental bearing secured within the recess D and in which thecenter portion of the rod G is journaled.

J is a bell-crank-shape arm secured at the lower end in the end of thebar H and having the upper bent end extending through an arc-shaped slotD in the end plate D.

I is a groove in the bottom of the door, which is so shaped as to permitthe tilting of the strip E, so that the outer edge may be forced downagainst the sill of the door.

E is a strip of felt, which I preferably place near the outer edge ofthe strip E in order to make the contact with the sill as close aspossible and prevent any openings underneath the edge of the strip. Thestrip E being a spring-strip may be forced down and will bend, andthereby from end to end insure the crevice being closed no matterwhether there is unevenness in the sill or not.

When the door is being closed the projecting end of the bellcrank-shapearm J contacts with the bracket C and forces down the outer edge of thestrip E against the sill so thatwhen the door is closed such edge isheld tightly against the sill and will effectually exclude draft frompassing under the crevice of the door.

It will be seen that immediately the door is open the slightest, theweight of the bar H will immediately cause the edge of the strip E torise and thus allow the door to be readily opened without any liabilityof the strip com ing in contact with the floor or sill. It will also benoticed that when the curled edge F rises it hugs the groove when thestrip is depressed, and thereby prevents a draft passing upwardly andaround through the groove.

What I claim as my invention is:

1. In a weather strip for the bottom of doors, the combination with thedoor having a longitudinal groove in the bottom thereof,

of thelorigit'udinal strip cam-prisin a'; sprin tom of the door assp'ecifie 2. In a'weather strip for the 'bo -ttom of doors, thecombination with the longitudinal strip comprising a'spring strip end e"folded "nrieiins on-the end of the stri "come in contact with the proection on the strip intdwhiohone edgeof the spring strip "fits providedwith a, curled edge, the end 1' plates, therod extending through thecurled edge and into journals in the end plates and designed to jzinibfor tilting the strip as and for the-pur- WILLIAM MALOTT.
